PROBLEM TO BE SOLVED: To eliminate troubles such as a disconnection or jamming in a presentation accessory device in a game machine, and more over accomplish this without causing a longer development period.SOLUTION: When a movable body 2000 moves from a first position to a second position, an upper board contact point PCU and a first contact point WCU come into contact with each other to enable a delivery of current and/or signals. When the movable body 2000 moves from the second position to the first position, a lower board contact point PCD and a second contact point WCD come into contact with each other to enable a delivery of current and/or signals. In this case, the lower board contact point PCD, caused by its own weight, contacts firmly to the second contact point WCD. The usage of a flexible cable becomes unnecessary and no dragging of a harness by the movable body occurs. |
